On September 6, Sulli shared a nostalgic post celebrating her 13th anniversary since debut!
One photo showed Sulli as a child actress, dressed in colorful hanbok for an acting role, while another photo showed all-grown-up Sulli taking a selca. She wrote, "13 years have flown by in the blink of an eye!! I feel that I am thankful toward those of you who had to watch me growing up. Het. I made a lot of mistakes along the way, but I think the reason I am able to continue smiling is that there were those beside me who believed in me and cheered me on. Thank you, and fighting from here on! Thank you for congratulating me on my 13th anniversary, Peaches."
Meanwhile, Sulli's former group f(x) celebrated their 9th anniversary on September 5.
